IMPROVEMENT IN GAS-BURNERS.

` Specification forming part of Letters Patent No. 222,479, dated December 9, 1879; application filed November 3, 1879.

To all whom it may concern:

Be it known that I, PoMPEo FALTONI, of Moncalieri, Italy, have invented a new and useful Improvement in Gas-Burners, which invention is fully set forth in the following specilication, reference being had to the accompanying drawing, which represen ts a vertical crosssection of a burner embodying my invention.

Myinvention relates to devices for automaticall y regulating the pressure of gas in gas-burners 5 and it consists in the combination, with a burner and a chamber below the burner, for attachment to a gas-supply pipe, of a laterally-perforated feed-nipple in the center of the chamber, and a fixed cap arranged upon the nipple, so that the gas is admitted to the chamber by means of the nipple, andvis retarded by the cap in its ow through the chamber; and since the latter partakes of the heat of the burner, the gas expands therein, thereby regulating the pressure and insuring a steady PIPB- The top of the chamber B 1s made detachable, to give access to its interior, and the feednipple G rises from its bottom in the center of the chamber.

The cap D is attached to the feed-nipple G,

' so as to occupy a fixed position, by means of a screw, g, which enters the upper end of the nipple, thus closing' the same at that point.

In the nipple G are lateral perforations h,

the same being above' the lower edge of the cap D and below the screw g.

I construct the cap D with a series of walls, i, to divide the same into as many spaces, and thereby increase its effect.

The gas supplied to the burner is received in the nipple C, and, passing through its perforations h, enters the chamber B, whence it flows to the burner. As the burner becomes heated by the gas-dame the chamber B also becomes heated, and as the gas enters the chamber it passes and repasses to and from the interior of the cap D, whereby it is retarded in its 110W through the chamber and is heated. In this manner the gas is caused to expand in the chamber B, and inasmuch as this expansion affects the inux of gas to the chamber, a uniform or steady iow of gas to the burner is obtained, and one which is equal only to the consumption.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with a gas-burner, A, and an enlarged expansion-chamber, B, constructed with a vertical tubular nipple, G, screwthreaded internally at its 'upper end and provided with lateral perforations h, of a gas-retarding cap, D, arranged over the nipple, and a screw, g, passing through the top of the cap into the screw-threaded end of the nipple, serving to close the upper end of the latter and at the same time secure the cap in a fixed position, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 11th day of July, 1879. f
